Defining Minerals Quiz - True/False + Fill in the blank

Hardness is the resistance of a mineral to breaking, not scratching.

Streak is the color of the mineral itself, not the color of the powder produced when it is dragged across a surface.

Friedrich Mohs created the scale of mineral hardness known as the Mohs scale of hardness.

Cleavage is the way a mineral breaks along definite crystallographic structural planes.

Minerals with no cleavage generally break with a regular fracture called a concoidal fracture.

Streak is the color of the ______ produced when it is dragged across a surface

Hardness is the resistance of a mineral to ______

Mohs scale of hardness ranges from the softest (1) to the ______ (10)

Cleavage is the way a mineral breaks/splits along definite crystallographic structural ______

Minerals with no cleavage generally break with irregular fracture called a ______ fracture

Streak is the color of the powder produced when it is dragged across a surface. The color could be different from the ______s color, and is always distinctive. Many ______s do not have a streak

Hardness is the resistance of a mineral to scratching. It is a property by which minerals may be ______ relative to a standard scale of 10 minerals. This is known as the Mohs scale of hardness

Cleavage is the way a mineral ______/splits along definite crystallographic structural planes. Cleavage can be in one plane or multiple planes

Mohs scale of hardness In 1812, Friedrich Mohs – famous geologist and mineralogist created a scale of mineral hardness grading from the softest (1) to the ______ (10). The scale was created using the simple technique of one mineral's ability to visibly scratch another

Minerals with no cleavage generally break in a more or less random pattern. Minerals with no cleavage generally break in a more or less random pattern. Minerals with no cleavage generally break with irregular fracture called a __________ fracture
